What do you want to know? I'm fairly sure that is the model I use, although if not mine is very similar.

You can calibrate any of the meters... on multiple points... as a means to test the ability of the meter to set across a range. Better meters will hold resolution at both the high & low ends.
For what we do... never going down to 4 or up to 10... just use the 7.0 solution. Though if you test on two or three points... you will better be able to see your meter go bad, over time.

I will just be testing at one point. What solution did you use for the ppm/tds?
